What are bailiffs legally allowed to take?

The bailiffs are due round at my house but it's for my dad's debt. I've got quite a lot of stuff including, laptop, tele, ps3 and iphone, but that is mine. Are they allowed to take my stuff for my dad's debt, and also do i HAVE to let them in?

Added (1). What's not to get lol. Bailiffs are coming round to collect debt off my dad. I live with my dad. He has nothing of value, but i do. Can they take my stuff? Simples

I have no idea what your talking about.

No you don't have to let them in. Don't open the door or they will lean on it and enter. Make sure all the ground floor windows are closed as they are legally allowed to enter through an open window,. The trouble with bailiffs is that they are thick and will take anything. So either move your kit or keep them out.

Absolutely no way can they take what is yours. But they may want proof it is yours.

You will need proof that the goods are yours. They can taken anything except the bed and the tools of the person's trade.

They're not allowed to take stuff that belongs to kids - how old are you?

Citizen's advice tells you all the things they are and aren't allowed to take - http://www.adviceguide.org.uk/wales/debt_w/debt_action_your_creditor_can_take_e/debt_bailiffs_e/what_happens_if_the_bailiffs_get_in.htm

But if you are an adult, then all you have to do is prove the stuff is yours, not your fathers, and not "part-owned" with him, if you have anything like bills or credit card statements with your name on, they should accept this. If they don't, you can then claim it back.
